Artificial christmas tree

ABSTRACT

An artificial Christmas tree includes a foot stand, a trunk, multiple branches and multiple leaves. One end of the trunk is connected with the foot stand. The trunk has multiple branch holders. Each branch is formed by sheathing plastic around an iron wire and is flexible and bendable. One end of each branch is connected with a corresponding branch holder of the trunk and each branch has multiple leafstalk seats formed around a periphery of the branch for corresponding leaves to be mounted on the leafstalk seats. Each leaf has a resilient metal wire sheathed by plastic and has multiple leaflets formed on the sheathed metal wire. As the leaves can be short or long and can be sequentially spread out after mounted on corresponding branches, a Christmas tree structure with simple and easy assembly and three-dimensional spatial perception to viewers can be attained.

BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates to an artificial Christmas tree and, moreparticularly, to an artificial Christmas tree rendering increased easeand convenience in assembly and shipment of the artificial Christmastree and quick shape restorability after the artificial Christmas treeis unpacked.

2. Description of the Related Art

In view of its simple assembly, complete and beautiful tree structure,and easy storage and relocation, undoubtedly, artificial Christmas treeis one of the most indispensable decorations during the Christmasholiday season. To give an artificial Christmas tree a natural andaesthetically appealing look, tree leaves are supposed to be correctlypositioned and oriented as desired.

However, tree leaves of artificial Christmas trees available in themarket must be manually adjusted by workers in the factory in terms oflocation and orientation of the tree leaves before shipment. Despite theavailability of standard operation procedures for assembly of theartificial Christmas trees, under the circumstance that aestheticjudgment varies from person to person and product capacity is a majormanufacturing concern, consistent and optimal shape of the artificialChristmas trees is hard to get. As warehousing and shipping costs arealso critical to be taken into account, the artificial Christmas treestend to be squeezed as much as possible especially when they are packedfor shipping. After consumers receive and unpack the purchasedartificial Christmas trees, tree leaves and branches of the artificialtrees appear to be folded and distorted, giving a tree structure muchless than expected by the consumers. Even though manufacturers of theartificial Christmas trees stress that the artificial Christmas treesmay be made of steel wire, which is more rigid and less damage-prone, itis inevitable that the artificial Christmas trees eventually becomedistorted due to the weight and poor elasticity of the steel wires.
